Number and dry weight of weeds was not significantly affected by various varieties. Nitrogen fertilization showed adverse effect on weed population. Harmful effect of nitrogen doses was, however, not marked on-dry ma'ter of weeds. Weed competition, as evident from weeds population and their dry weight was practically nil in WI (hand weeded) plots. Superiority of 2,4-0 was also significant over control (No Weeding). The reduction in weed competition by 2, 4-0 was about the same (34 and 36 per cent) during 1963 and 1964 respectively. Increase in every gram of dry weight in weed per square metre reduce the grain yield by 0.09 gram per plant, Most of the broad leaved weeds were susceptible to the 2, 4-0 sprayings.
